Reamer Sets

Our Fast Spiral Reamers feature a tight spiral that is very aggressive as well as a stop collar that stops the reamer when it has gone all the way through a hole. They are made from Hi-Tungsten tool steel and have a black and gold coating for maximum lubricity. They are designed to enlargen holes in structural steel plates found in truck frames, rail cars, bridges, and pressure vessels. Sizes 1/4"-3/8" feature a shank the same size as the cutting diameter and sizes 7/16"-1-1/4" feature a 1/2" reduced shank with three machines flats for added chuck grippage. Made in the USA by Norseman Drill & Tool.
